Answer:

7, you are correct

Step-by-step explanation:

Just count the units across.

Tthe non-zero scalar 'k' such that vector C is equal to the sum of vector A and k times vector B, we can solve the equation C = A + kB. By substituting the given values of vectors A, B, and C into the equation, we can determine the value of the scalar 'k'.

Let's consider the equation C = A + kB, where C, A, and B are vectors, and k is the scalar we need to determine. Substituting the given values, we have:

C = A + kB

(0) = (3, -12) + k(-1, 4)

Expanding the equation, we get:

(0) = (3 - k, -12 + 4k)

From the equation, we can derive two separate equations for the x-component and y-component:

0 = 3 - k (for x-component)

0 = -12 + 4k (for y-component)

Solving the first equation for k, we find:

k = 3

Substituting this value into the second equation to check if it holds true:

0 = -12 + 4(3)

0 = -12 + 12

0 = 0

Since both components of the equation evaluate to 0, the scalar 'k' is 3. Thus, C = A + 3B.

Answer:

Difference in the lengths of the polygons is (x + 7) units.

Step-by-step explanation:

Lengths of the given polygon = (7x + 2) units and (6x - 5) units

Therefore, difference in the given lengths = (7x + 2) - (6x - 5)

                                                                      = (7x - 6x) + (2 + 5)

                                                                      = x + 7

Therefore, difference in the lengths of the polygons is (x + 7) units.

3) Case 3: if: degree of numerator > degree of denominator.

This measure of central tendency can be considered the most precise in option c. mean

The mean is a measure of central tendency that calculates the average of a set of values. It is often considered the most precise measure because it takes into account all the values in the dataset and provides a balanced representation.

The mean is calculated by summing all the values and dividing by the total number of values. Unlike the mode, which only identifies the most frequently occurring value, and the median, which represents the middle value, the mean incorporates all the values and provides a comprehensive summary of the dataset.

However, it is important to note that the mean can be sensitive to extreme values or outliers in the data.

The thickness of the clay layer, which drains only from the upper surface, can be determined based on the consolidation settlement observations. With 50% of consolidation settlement occurring in 1 hour for a 25 mm thick specimen, and a total primary consolidation settlement of 35 mm occurring over many years, the thickness of the clay layer is approximately 87.5 mm.

The consolidation settlement of a clay specimen can be used to estimate the thickness of a clay layer that drains only from the upper surface. In this case, the observed settlement data provides valuable information.

Firstly, we know that 50% of the consolidation settlement occurs in 1 hour for a 25 mm thick clay specimen. This is an important parameter for calculating the coefficient of consolidation (Cv) using Terzaghi's theory. From the Cv value, we can estimate the time required for full consolidation settlement.

Secondly, we are given that the same clay settles 10 mm over 10 years and eventually settles a total of 35 mm over a longer period. This long-term settlement is known as the total primary consolidation settlement. By comparing this settlement value with the settlement data from the oedometer test, we can determine the thickness of the clay layer.

To calculate the thickness, we can use the concept of the consolidation settlement ratio. The ratio of the total primary consolidation settlement to the consolidation settlement at 50% completion is equal to the ratio of the total thickness to the thickness at 50% completion. Applying this ratio, we can determine that the thickness of the clay layer, which drains only from the upper surface, is approximately 87.5 mm.

Answer:

because g(n) = 2.g(n - 1) => this is a geometric progression

=> g(n) = 3.2^(n-1)

Step-by-step explanation:

45 Distinct handshakes took place when every player shook hands with everyone who played.

To find out how many distinct handshakes took place if every player shook hands with everyone who played, we will

use the concept of combinations.

Identify the number of players involved, which is 10 (you plus 9 friends).

Use the formula for combinations: C(n, k) = n! / [k! × (n-k)!],

where n is the total number of players and k is the number of players in each handshake (which is 2).

Plug in the values: C(10, 2) = 10! / [2! × (10-2)!].

Calculate the factorial values: 10! = 3,628,800, 2! = 2, and 8! = 40,320.

Plug in the factorial values and calculate: C(10, 2) = 3,628,800 / (2 × 40,320) = 3,628,800 / 80,640 = 45.

So, 45 distinct handshakes took place when every player shook hands with everyone who played.

the required sample size is approximately 178. Answer (c) is correct.To determine the required sample size, we can use the formula:

n = (z * σ / E)^2

where:
- n is the sample size
- z is the z-score for the desired level of confidence (99% corresponds to z = 2.58)
- σ is the standard deviation of the population
- E is the maximum error we want to allow in our estimate of the population mean

The likelihood that a data is within two standard deviations of the mean

By observation, the distribution depicted in the task content above is a normal distribution.

One can tell the difference between the following .

In the case of a standard normal distribution, 68% of the observations (datum) are within one standard deviation of the mean, 95% are within two standard deviations of the mean, and 99.9% are within three standard deviations of the mean.

There are 287.5 calories in 25 potato chips. Therefore, option B is the correct answer.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, 10 potato chips contain 115 calories.

Number of calories in one potato chips = Total number of calories ÷ Number of calories

= 115/10

= 11.5 calories

Number of calories in 25 potato chips

The equation of the circle, obtained by applying the completing the square method to the specified equation indicates that the center and radius of the circle are;

Center (0, 6) and radius 7.5

The general form of the equation of a circle is; (x - h)² + (y - k)² = r², where;

(h, k) = The coordinates of the center of the circle

r = The measure of the length of the radius

The possible equation obtained from a similar question on the internet can be presented as follows;

x² + y² - 12·y - 20.25 = 0

The above equation can be evaluated using the completing the square method and excluding the x² term as follows;

y² - 12·y - 20.25 = 0

y² - 12·y = 20.25

y² - 12·y + (-12/2)² = 20.25 + (-12/2)²

y² - 12·y + (-6)² = 20.25 + (-6)² = 56.25

(y - 6)² = 56.25

Therefore;

y - 6 = √(56.25) = ±7.5

The possible equation of the circle obtained by plugging in the x² term therefore is; (x - 0)² + (y - 6)² = 7.5²

The center of the circle is therefore;

(h, k) = (0, 6)

The radius of the circle, r = 7.5

The probability that less than 5 employees were over 50 is approximately 0.5637, or 56.37%.

To calculate the probability that less than 5 employees were over 50, we need to consider all possible combinations of dismissing employees.

1: Determine the number of ways to choose less than 5 employees over 50.

We can choose 0, 1, 2, 3, or 4 employees over 50.

For choosing 0 employees over 50:

Number of ways = C(16, 6) = 8008

For choosing 1 employee over 50:

Number of ways = C(9, 1) * C(16, 5) = 9 * 4368 = 39312

For choosing 2 employees over 50:

Number of ways = C(9, 2) * C(16, 4) = 36 * 1820 = 65520

For choosing 3 employees over 50:

Number of ways = C(9, 3) * C(16, 3) = 84 * 560 = 47040

For choosing 4 employees over 50:

Number of ways = C(9, 4) * C(16, 2) = 126 * 120 = 15120

2: Calculate the total number of ways to choose any 6 employees from the total pool of 25 employees.

Number of ways = C(25, 6) = 177100

3: Calculate the probability by summing up the number of ways from Step 1 and dividing it by the number of ways from Step 2.

Probability = (Sum of number of ways from Step 1) / (Number of ways from Step 2)

Probability = (8008 + 39312 + 65520 + 47040 + 15120) / 177100

Probability = 56.37%
